Family protection and prevention of alcohol use among Hispanic youth at high risk.

Research regarding prevention strategies for Hispanic youth stress the importance of family interventions because of the particular importance of family as a protective factor within the Hispanic community. Starting in 1995, the Center for Substance Abuse Prevention conducted the National Cross-Site Evaluation of High Risk Youth Programs, a 5-year drug and alcohol prevention study with a sample of approximately 10,500 youth, including nearly 3,000 Hispanic youth. Youth were surveyed regarding their alcohol use patterns and risk and protective factors, with several measures of family relationships, including family connectedness, family supervision, and parental attitudes toward their child's alcohol use. Analyses indicate that family factors are highly linked to alcohol use among Hispanics, particularly among Hispanic females. Longitudinal growth curve analyses indicate that improving the connections that young Hispanic females have to their parents can have positive long-term effects on delaying or reducing their alcohol use.

Understanding prevention effectiveness in real-world settings: the National Cross-Site Evaluation of high risk youth programs.

The National Cross-Site Evaluation is a large multisite evaluation (MSE) of 48 substance abuse prevention programs, 5,934 youth participating in programs, and 4,539 comparison youth programs. Data included a self-report questionnaire administered at 4 points in time, detailed dosage data on over 217,000 program contacts, and detailed site visit information. In a pooled analysis, the programs did not demonstrate significant positive effects on a composite outcome measure of tobacco, alcohol, and marijuana use in the previous 30 days. However, disaggregated analyses indicated that 1) sites in which comparison groups had strong opportunity to participate in prevention programs suppressed observed effects; 2) youth who had already started using before they entered programs reduced use significantly more than comparison youth who had started using; and 3) both males and females who participated in programs significantly reduced use relative to comparisons, but in very different patterns. Combining these patterns produced an apparent null effect. Finally, programs that incorporated at least 4 out of 5 effective intervention characteristics identified in the study significantly reduced use for both males and females relative to comparison youth. The lessons produced by this study attest to the value of MSE designs as a source of applicable knowledge about prevention interventions.

Risk, protection, and substance use in adolescents: a multi-site model.

This article reports findings from a national longitudinal cross-site evaluation of high-risk youth to clarify the relationships between risk and protective factors and substance use. Using structural equation modeling, baseline data on 10,473 youth between the ages of 9 and 18 in 48 high-risk communities around the nation are analyzed. Youth were assessed on substance use (cigarette, alcohol, and marijuana use), external risk factors including family, school, peer and neighborhood influences, and individual risk and protective factors including self-control, family connectedness, and school connectedness. Findings indicate strong direct relationships between peer and parental substance use norms and substance use. Individual protective factors, particularly family and school connectedness were strong mediators of individual substance use. These findings suggest that multi-dimensional prevention programming stressing the fostering of conventional anti-substance use attitudes among parents and peers, the importance of parental supervision, and development of strong connections between youth and their family, peers, and school may be most effective in preventing and reducing substance use patterns among high-risk youth.

Predictor variables by developmental stages: a center for substance abuse prevention multisite study.

Five articles present the results obtained in a multisite study funded by the Center for Substance Abuse Prevention (CSAP). The overarching goal of this effort was to determine the efficacy of reducing severity of factors during childhood that are known to magnify the risk for substance abuse (SA) in adolescence. The factors targeted for preventive intervention were Behavior Self-Regulation, Parental Involvement, School Bonding, and Social Competence. Conceptualizing SA within a developmental framework, the findings indicate that prevention directed at youth between 3-14 years of age has a significant positive impact on attenuating intermediary factors predisposing to SA. In this introduction, both the theoretical framework and rationale guiding this cooperative agreement and the key findings are described.
